Find Haskell engineers and maintainers

The list above ranks the most-starred public Haskell repositories, drawn from the public GitHub graph. Across 1,098 Haskell repositories in the public graph, the maintainers, top contributors, and recurring committers are a powerful signal for where Haskell expertise lives.

Behind every popular Haskellproject is a small group of people who actually shipped it. They’re the Haskellengineers, library authors, and infrastructure builders worth knowing - whether you’re hiring, partnering, or doing technical research.

Refolk turns this list into a search. Ask for “Haskell maintainers hiring”, “contributors to Haskell repos based in Europe”, or “companies whose engineers ship Haskell” and Refolk returns a ranked shortlist with the commits, repos, and profiles that earned each person a spot.

How this list is built

Refolk searched GitHub for public repositories whose primary language is Haskell, ranked them by stargazer count, and kept those with at least 100 stars. The list refreshes once a day.
